The magazine reports that the Camaro will switch to General Motors Alpha platform as expected, but that it will be based on the long-wheelbase version used by the Cadillac CTS, not the short-wheelbase version used by the ATS.

At 114.6 inches, that would leave the 2016 Camaro with a wheelbase 2.3 inches longer than the current car's and 7.5 inches longer than the 2015 Ford Mustang's, but slightly shorter than the current Dodge Challenger's wheelbase.

The growth may be planned to allow room for a smaller sports car that could compete with the Subaru BRZ/Scion FR-S twins and the Mazda MX-5 Miata. This entry-level model could be based on either the rear-wheel-drive Code 130R or front-wheel-drive Tru 140S concepts from 2012.

In the powertrain department, the 2016 Camaro may also get a four-cylinder engine option, likely a version of the 2.0-liter turbocharged unit that produces 272 horsepower and 295 pound-feet of torque in the Cadillac ATS and CTS. Of course, V-6 and V-8 units should continue to be available.

The obvious bogey here is the 2015 Mustang EcoBoost, although Chevy may need to tweak its engine a bit to match Ford's 2.3-liter, which is promised to deliver more than 305 hp and 300 lb-ft of torque.

The new Camaro is expected to make its first public appearance in early 2015, and go on sale later that year.
